Maybe. All I remember is that god awful "Wistleblower" song. Just cringeworthy shit right there. But they still played instruments, even though they were playing on National television to thousands of viewers. THOUSANDS!
I think so. It makes complete sense that you can't set up a full stage with lighting, pyro, and sound equipment in less than 7 minutes. Then, tear the whole thing down again just as quickly. I read a while back that that was the case with The Who a few years ago too. They recorded everything live at a dress rehearsal a few days prior so it still felt like a live performance.
